In case you really love Drupal, you can use Open Atrium to setup your own Web-based project management website, create complex Web portals or even run entire company Intranets.

Open Atrium is free script that adds new features on top of the famous Drupal CMS that will allow webmasters more control over data sharing, custom dashboards, document sharing, project tracking and so on.

It was created so it can allow users an easier way for sharing data and following each others without the admin needing to install tens or hundreds of smaller Drupal modules.

Open Atrium can be easily deployed anywhere and will work just like any Drupal site, but benefiting from a much more easier to manage administration interface.

Because Open Atrium is basically Drupal at its core, it's also easy to extend, easy to scale up or down and as easy to customize as any Drupal site.
